General Information

Moving Geometer Caterpillar
[an error occurred while processing this directive]

Geometer caterpillars camouflage by pretending to be a twig. With their front part they hold fast to a twig while stretching the back part away from the twig.

The way they move is also very extraordinary. Look at the film to know why they are called Geometers.
